I have svg xml that i can convert to ImageSource or FileImageSource by using XamSVG library in the PCL project of my xamarin.forms.
I want to convert the ImageSource / FileImageSource to byte array (to get the bitmap).
Is this possible ?

ImageSource doesn't expose any mechanism to retrieve the original image source. Instead, you will need to manually keep a reference to the original source you use to create the image.
I've found the solution.
StreamImageSource streamImageSource = (StreamImageSource) some image source...
System.Threading.CancellationToken cancellationToken = System.Threading.CancellationToken.None;
Task<Stream> task = streamImageSource.Stream(cancellationToken);
Stream stream = task.Result;

a is streamImageSource

This is not a solution - it only works if the
ImageSource is of type StreamImageSource. It is not away to create an output stream of any ImageSourceAnother solution:
public static byte[] ReadFully(Stream input)
{
using (MemoryStream ms = new MemoryStream())
{
input.CopyTo(ms);
return ms.ToArray();
}
}
Stream and MemoryStream are System.IO classes.
Then use it like this:
byte[] TargetImageByte = ReadFully(_data.Source);
_data.source is MediaFile type.
